Abstract
A resection instrument, especially for the minimally invasive, subanodermal, submucous removal of hemorrhoidal tissue, comprises a narrow oblong carrier provided with a resection portion for removing tissue on a front part. In order to improve a resection instrument such that tissue can be resected precisely and as gently as possible by handling the instrument in the easiest possible way it is suggested according to the invention that the resection portion has a trough-like bulge being curved in a convex manner and approximately spoon-shaped in the longitudinal section, with a resection surface provided with a resection element being disposed on the inner side of the trough-like bulge.

Resection instrument, especially for the minimally invasive, subanodermnal, submucous removal of hemorrhoidal tissue, comprising:
- a narrow oblong carrier means provided with a resection portion for removing tissue on a front part thereof, wherein the resection portion is provided with a trough-shaped bulge being curved in a convex manner and approximately spoon-shaped in the longitudinal section;
- and
- a resection surface provided with a resection means for resectioning tissue disposed thereon, the resection means being embedded on the inner side of the bulge and deviating from a longitudinal direction of the instrument wherein a peripheral portion of the spoon-shaped resection portion surrounds the resection means.
A resection instrument, comprising:
- an elongated holder portion having a longitudinal axis;
- a curved terminal portion having a substantially convex shape with respect to the longitudinal axis to define a cavity, the terminal portion being elongated in a direction transverse to the longitudinal axis;
- and
- a resection device having a resection surface to resect tissue, the resection device being embedded within the cavity along the resection surface in a location deviating from the longitudinal axis wherein a peripheral portion of the terminal portion surrounds the resection device.
